Devils washtub is located in Inks Lake National park. This is a state park found in United states of America, Burnet County, Texas. The landscape of the park is hilly with many cedar, live oak, cacti and Yuccas. The ground of the park is rocky, mainly consisting of Gneiss rock. The park has a natural forest known as Ghost Forest.
The Devils washtub / waterhole is a small extension of the Inks Lake National Park, which is almost completely surrounded by rocks. Tourists visiting the area conduct canoe tour within the Devils Waterhole. Diving and swimming is also done but without a lifeguard, at personal risk. The park also acts as a habitant for wildlife such as quail, deer, vultures and other many varieties of birds.The rocks within the Devils washtub are dated 1,232 million years old. The field trip was carried out to investigate the to investigate the geology of the area.
The main type of rocks found within the area was Gneiss, quartzite, granite and amphibole/amphibolite.The most Common rock within the Devilstub - Gneiss is a laminated metamorphic rock similar to granite. It is a course grained metamorphic rock formed sedimentary rocks through regional metamorphism. The field research showed that these rocks contained a wide range of minerals, such as feldspars, quartz, mica minerals, aluminous and ferromagnesian silicates. The gneiss rocks were also found to contain some amounts of iron, nickel , silicon and cobalt.
The granite rock among feld spar, quartz and mica also contained diamond and chalk.Some parts within the Devils water-mouth also contained the amphibolite rock. These kind of rock were found to contain some amounts of feldspar with little amounts of quartz.
The trip study also showed that these rocks had severally undergone metamorphism,a change in the structure of rock by natural agencies such as pressure, heat or introduction of new chemical substances. For instance, the high temperature conditions,and pressure beneath
